IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 174,756, dated March14,1876; application filed August 14, 1875.

To all whom it may concern:

Be it known that I, ABNER S. BAKER, of Kalamazoo, in the county ofKalamazoo and in the State of Michigan, have invented certain new anduseful Improvements in Seed- Planters and Cultivators and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings and to theletters of reference marked thereon, making a part of thisspecification.

This invention relates to an improved broadcast seeder and cultivator,or gang-plow, combined; and it consists in a improved combination ofdevices for raising the rhomboidal frame or truck, for the purpose ofthrowing the beveled wheels out of gear, consisting of two compoundlevers working in standards attached to opposite sides of the frame, andprovided with devices for fastening the same in any desired position,said levers being connected with vertical standards to which the wheelsare journaled, and which slide in ways formed upon standards or platesattached to the machine on opposite sides, as more fully hereinafterdescribed.

In the drawings, Figure 1 represents a top view of my improvedapparatus. Fig. 2 represents a perspective view of the same. Fig. 3represents a section through the line or y of Fig. 1. Fig. 4 detachedviews of the right and left plows; Fig. 5, a detached view of one of thecompound levers, and Fig. 6 a detached view of the short and maintongues and the adjustable caster.

The letter A represents a strong frame or truck constructed in the formof a rhomboid or oblique-angled parallelogram, and B the Wheels uponwhich it is mounted. The said wheels are journaled on short journals onthe lower ends of the vertical standards 0 U, which are flanged on eachside, and are held in ways d d in the standards or plates D D, which aresecured to opposite sides of the frame A, and in which said standards 0O are adapted to move vertically. E E represent two slotted verticalstandards mounted on the top of the frame A, on opposite sides thereof,and F F two compound levers passing through the slots and adapted towork therein. Said with, its front edge.

compound levers consist each of two levers, f and f. The lever f isslotted longitudinally at its center, and one end attached to theslotted head of the standard 0, theother end being pivoted to the leverf between its fulcrum or point of attachment g and its handle. Eachstandard, O has formed on one side a toothed segment, G, to the side ofwhich the handle of the lever f works, said lever being provided'witha'hand pawl, H, which engages the teeth of the segment, but which can besents the seed-box extending across the front of theframe, directlybehind, and parallel Said box is of a trian gular shape, the apexdownward, an opening being left its entire length at the bottom, inwhich there is 'located a recessed shaft or roller, 1, which is capableof a rotary movement, and forces the seed from the box to thedistributing-board K below. The said boxI is provided with a series ofequidistant partitions, i, and a gage-plate, L, on the inside, securedto one of the sides by means of setscrews 1 passing through 7 slotstherein, by which it is rendered adj nstable to regulate or gage theseeds dropped from the box. Said roller or shaft has secured to one enda pulley, M, which is connected by a belt, chain, or band, with asimilar pulley, N, mounted on a short shaft, 0, journaled in anadjustable hanger, P, attached to the frame A. other end of saidshaft'is mounted with a beveled gear-wheel, Q, which meshes with alarger beveled gear-wheel, R, secured to the wheel B of the machine.This gearing serves to transmit the power from the wheels of the andforce the seeds from the seed-box.

under, and parallel with, the seed-box, inclin- The 1 from side to sideof the machine from one acute angle to the other thereof, all beingturned in the same direction, as illustrated, when the machine isemployed as a seeder for sowing-broadcast. For cultivating corn,however, I provide two interchangeable shares turning in. oppositedirections, as indicated by the letter A Fig. 4, which are attached andused as hereinafter explained. The letter B represents a short tongueattached to the front of the frame A. To one side of said tongue isattached, by means of a screw-bolt b, a slotted standard, to which isswiveled a caster, C. By this means the tongue and frame can be elevatedor lowered at will to regulate the depth of the plows, as will beevident. To the front end of the short tongue is also secured adepending yoke or shackle, D, through which the main tongue E sets,being hinged or pivoted at its rear end to the short tongue at F. Saidyoke or shackle is provided with apertures 01 on opposite sides, and thetongue with a similar aperture, through which a pin may be inserted forsecuring the tongue F rigidly and adjusting the same, or it may be leftfree as may be desired.

In employing the apparatus for corn I make use of the reverse shares AFig. 4. I detach the seed-box, or, disconnect the gearing by which theseeder-is driven, and then take out the middle-share leg, leaving threeshares or teeth each Sl(IG )f LhQIOV of corn, and by means of thereverse teeth can throw the soil to or from the rows at pleasure.

When the corn is young, in which case it is necessary to throw the soilfrom the rows, I take 011' the right-hand share or tooth from the middleleg of the left-hand side of the frame, and the right-hand tooth orshare from the righthand side of the same, and substitute in theirplaces the left-hand or reverse teeth. After the plant has grownsufliciently to stand the soil necessary to form the hill, I take thetwo left-hand teeth, and place themone on the left-hand leg on theleft-hand side of the frame, and the other on the middle leg of theright-hand side of the frame, in which position they will turn all weedsand grass into the hill. For summer fallow the machine is employed, asfirst described and illustrated, with the exception of the seedingattachment.

Having fully described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-- The combination,substantially as described, of the compound levers F ff working onstandards E attached to frame A, and the standards G working in platesor standards D, and carrying the'wheels B, on which the truck issupported, for the purposes set forth. I

In testimony that I claim the foregoing I have hereunto set my hand this27th day of April, 1875.
